Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742936, here are decompositions:

5 + 8742931 = 8742936
17 + 8742919 = 8742936
19 + 8742917 = 8742936
79 + 8742857 = 8742936
89 + 8742847 = 8742936
149 + 8742787 = 8742936
157 + 8742779 = 8742936
197 + 8742739 = 8742936

Showing the first eight; more decompositions exist.
